GetRasterProjectorSection()

RasterProjector * Maria::RasterProjectorFactory::GetRasterProjectorSection	(	RasterProjector *	rp,
		const BasicGeoTypes::PointDXY &	xy,
		int	w,
		int	h
	)

Gets a rasterprojector as a translation/section of a given rasterprojector, keeping the same geoprjector. rp : input rasterprojector xy : point (pixel coordinates) in input rasterprojector corresponding to (0,0) in new one. (Maps to the same geogrphic point). w, h : desired with and height in pixels.

GetTileProjector()

RasterProjector * Maria::RasterProjectorFactory::GetTileProjector ( RasterProjector *  tileBase, int  tileSize, int  lvl, int  tx, int  ty, bool  pointPixel = false  )

inline

Get a rasterprojector for a given tile in a given tiling. This method will generate a raster projector for the tile given by the tile index (lvl, tx, ty), and given resolution. If the pointPixel flag is set, the raster projector will be extended by a half pixel in all directions, so that the XY coordinate system is a set of grid nodes, instead of area pixels. This is useful when converting datasets from area grids to point pixel grids, but should not be used on general datasets.

New()

RasterProjector * Maria::RasterProjectorFactory::New	(	const std::shared_ptr< RasterProjector > &	tileBase,
		double	x0,
		double	y0,
		int	w,
		int	h
	)

Get a rasterprojector for a subtile image.

Parameters

tileBase	basetile raster projector
x0
y0	x0,y0 is image coordinates of upper left corner in basetile corresponding to 0,0 in desired subtile
w	with of desired subtile in pixels
h	height of desired subtile in pixels
